TEMPLE- ROLLER.

SPECIFICATION forming part of Letters Patent No. 239,467, dated March 29, 1.881.

Application filed January 27, 1879.

teeth are equidistant from the end of the roller,

and the adjacent teeth of the rows of teeth are about one-eighth of an inch apart. This ordinary temple-roller when in use extends from the selvage pf the cloth inward parallel with the cloth-makingpoint, or nearly so, and in thin cotton goods, and in dress-goods or thin goods having worsted filling, it has been found that the successive teeth of each annular row of teeth follow the cloth-making point threads.

(or last weftlaid between the warps) so closely that there is not enough cloth formed between the points of penetration of teeth following in the annular rows of teeth as will afford such an engagement of the teeth with the cloth as will prevent the contraction of the cloth sliding warp-threads out of place on the filling when, owing to the position of the reed and warps, some two teeth of one annular row penetrate insuccession between the same two warp-threads. With this my improved teniple-roller the teeth are so placed as not to act to move the warps longitudinally with relation to the filling, and so make gaps or open spaces in the cloth being woven.

My invention is shown as embodied in a wooden roller provided with steel cloth-penetrating pins iusertedtherein and projecting therefrom radially, so that no two teeth of the said roller will so closely follow each other in the same line as to displace any of the warp- Gonsequently each following tooth of a roller provided with teeth in accordance with my invention must be so far removed from the tooth in advance of it in the same linetha-t when one of the said teeth penetrates and extends through the cloth at the cloth-making point, another tooth in the same line will not penetrate the cloth or arrive in position substantially at the cloth-making point until a sufficient number of threads of weft have been introducedto withdraw from the cloth the pin in line with it at the rear of the cloth-making point. In other words, no two teeth will 5 5 follow each other so closely in the same line as to displace any of the warp-threads before the other pin in the same line and at the same distance from the end of the roller is at such a distance from the cloth-making point that the cloth,where so engaged by one of the pins, is no longer subject to the influence of the different sheds of warps while the filling is being beaten in by the reed. The fully-formed cloth will be more or less removed from the last weft 6 laid and acted upon by the reed according to the class of fabric. The cloth is subjected to the influence of the reed and tension of the warps in shedding until the weft is beaten up as fully as it will or can be by the reed.

In practice I have found, for the best results, that no two teeth at exactly the same distance from the end of the roller, or inthe same annular line, should follow each other closer than three-eighths of an inch apart. I prefer to place the teeth in one or more true spiral rows, in which case two teeth will never exactly follow each other, and two succeeding teeth will tlierefore'never enter between and pass through the cloth between. the same two warp-threads.

Iron temple-rollers have been provided with burrs struck up from the surfaces of the said rollers and shaped to resemble pins, and said burrs have been irregularly set or formed; but in all such rollers the teeth have been of such form and set at such an angle with relation to the surface of the rollers that the said teeth scratch or scrape upon the cloth and do not, nor can they, pass through the interstices between two adjacent warp-threads by the move- I am aware that a frictional covering of cardfillet has been applied to temple-rollers; but the teeth of the said fillet were not constructed to penetrate the cloth in the interstices between the warp and filling-threads, as do the teeth in connection with my improved roller.

An iron roller soon rusts. The teeth cannot be made hard and fine, as can steel pins, such as used in wooden rollers, and if broken cannot be replaced. The wooden roller does not require to be lubricated, as does the iron roller.

Figure 1 of the accompanying drawings shows a wooden temple-roller supplied with pins located in accordance with one form of my invention. Fig. 2 is a diagram representing such a roller, supposing it cut open longitudinally and laid out flat; Fig. 3, a similar view, the roller being provided with two spiralrows of teeth. Fig. 4 is a modification showing the teeth set in curved lines; Fig. 5, yet another modification, in which the teeth following each other in annular rows are removed each from the other farther than ever before practiced. in order to make my invention available when the pins are placed in proper annular rows; and Fig. 6 represents the common roller upon which my invention is an improvement.

' The roller or shell to shown is supposed to be of wood, and the pins 1) to be of steel, the pins being inserted into the roller or shell by any usual means.

In my invention, instead of placing the pins in annular rows-the pins of each row following closely one after the other, as shown in Fig. 6, which represents one of the most common forms of temple-rollers, wherein each annular row contains twelve teeth at substantially three-sixteenths of an inch each from the other-I place the teeth in a spiral row, as in Figs. 1 and 2, wherein it will be seen that no two teeth follow in exactly the same line or are, at'exactly the same distance from the end of the roller.

Fig. 3 shows the teeth placed in two spiral lines, and no two teeth at exactly the same distance from the end of the roller.

Fig. 4 shows the pins set in waved lines, and pins which fall at the same distance from the end of the roller are so far separated as to operate as described for my improved roller, and in Fig. 5 I have shown the pins in the same line sufficiently remote one from the other to operate as hereinbefere described, and in accordance with my invention or plan.

I claim- As an improved article of manufacture, the described temple-roller provided with teeth b placed therein, as set forth, to readily penetrate and hold the cloth, and set in lines, substant-ially as described, to prevent the penetrating of one tooth at the cloth-makin g point, while another tooth located at the same distance from the end of the roller is in such position between the same two warp-threads as to slip the warp upon the filling and form open spaces in the cloth, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE DRAPER.
